Finally, the second-round pick got his man. He dropped Sorensen for a 6-yard loss on third-and-15 from the Dallas 46 late in the third quarter.

“It was a gang,” Gregory said. “Me and [defensive tackle Davon] Coleman. Really what it is, he gets up field, and I act like I’m getting speed and then come back under him. He set it perfectly for me. I give him a lot of credit for that sack, but in the stat book it says me.”

Gregory recorded 25.5 sacks in two seasons at Nebraska, including 17 last season. He hopes Thursday’s sack was the first of many.

“Hopefully,” he said. “If I was a betting man, I’d say yeah, but obviously there’s a process with that. I’m going to enjoy that process. I’m going to work hard. They’re hard earned. They don’t come easy. You saw that today going up against even the second team and third team. They don’t come easy.”

DeMarcus Ware, the team’s all-time sacks leader, had only eight sacks in his rookie season of 2005. DeMarcus Lawrence, a second-round pick in 2014, missed nine games as a rookie but didn’t make his first sack until the postseason.
